In what position should the bonding connection be made when installing a GEC in a raceway?

The correct approach to bonding a Grounding Electrode Conductor (GEC) in a raceway is to make the connection at both ends of the raceway. This ensures a reliable and effective electrical pathway for grounding and bonding. When the GEC is bonded at both ends, it facilitates the dissipation of fault current and ensures a low-resistance path back to the grounding system.

Making the bonding connections at both ends of the raceway provides redundancy and enhances the integrity of the grounding system. It also helps in complying with the National Electrical Code (NEC) requirements, which aim to mitigate the risk of electrical shock and equipment damage by ensuring proper grounding.

The other options emphasize singular locations for bonding, which may not provide the same level of safety and effectiveness in the grounding system. Connecting near the ground rod or close to the panel may not accommodate the full length of the raceway, leaving potential weak points in the grounding system. The midpoint bonding may insufficiently address issues that may arise along the raceway's length, limiting the grounding effectiveness. Thus, establishing connections at both ends stands out as the best practice in ensuring a robust grounding approach when installing a GEC in a raceway.
